Surface-Atmosphere Feedbacks

CCR has extensively studied surface-atmosphere interactions linking vegetation, soil moisture, snowpack, lakes, and topography to atmospheric processes. Ecosystem-atmosphere exchanges of trace gases have been measured at flux towers across Midwestern wetlands/forests. Modeling and statistical methods have been applied to explore the impact of Rocky Mountain snowpack on the North American monsoon, the Great Lakes’ influence on regional climate, the capacity of afforestation to slow anthropogenic warming, the global monsoons’ sensitivity to vegetation feedbacks, and oceanic versus terrestrial drivers of drought. The observational and remote sensing analysis of Middle Eastern dust storms has offered the potential for seasonal prediction. Using models and proxy data, CCR has studied abrupt African climate-ecosystem change during the mid-Holocene and impacts of Tibetan uplift on the Asian monsoons.
